11.3 When a function does not work
11.3.1 General
ProblemCause & Solution
The unit does not work.LCheck the connections (page 21, 32).
The output tray becomes full 
quickly or the recording 
paper does not stack properly 
on the output tray.LHigh humidity may cause the recording paper to curl. Try turning the paper

modes. If you still have this problem, contact our service personnel.
A printing error is displayed 
while using PC FAX and 
Remote Control (KX-
